st: help merge when dataset have different size

[ncdcta00@uniroma2.it]

dear all, I have another question about merge:
I  have a dataset for the family wich the keys are:  country
hid(household idnt.) and another wich for the person  wich the keys
are:country pid hid.

In this second dataset the number of hid is grater than the first.
When make the merge is create a confusion, I use the second dataset
how using and the first how master.

make the merge in this procedure:
merge country hid  using... and take only the merge==3
Is't correct? because my results is very stranger....

thanks a lot for your help that is very useful...
best,
